The whole universe has only 5% of planets, stars, suns, moons and gases.

Astronomers are into a research and say that the universe is full of dark energy. This dark energy is composed of dark matter which affects the rate of universe expansions.

The dark matter also contains WIMPS (weakly interacting massive particles) which has the weight of the nuclei. The WIMPS never interacts with any matter. The dark matter in the universe is having a large amount of gravitational force which holds the universe together. Scientists are now detecting how this black matter helps in the structure of the universe.
